Description
- This is a §371 of International Application No. PCT/DE2008/001589, with an international filing date of Sep. 26, 2008 (WO 2009/039846 A1, published Apr. 2, 2009), which is based on German Patent Application No. 10 2007 046 520.5, filed Sep. 28, 2007, the subject matter of which is incorporated by reference.
- This disclosure relates to a light-emitting surface element and to a method for producing a light-emitting surface element.
- Light-emitting surface elements have acquired great importance in the recent past. Light-emitting surface elements are desired not just in cases where surfaces are to be illuminated areally as display elements, for example, but also in the case of a wide variety of types of displays. Particular importance is attached to a uniform luminous distribution of the light-emitting surface such that all regions are perceived equally. By way of example, LCD monitor and TFT displays, requiring areal transillumination, have existed for a relatively long time. However, light sources are generally in point or line form, such that the light has to be distributed over the surface for areal illumination. For this purpose, planar optical waveguides are known which, adapted to the distance from the light source by means of a corresponding surface treatment, couple the light out of the optical waveguide and cause it to be emitted.
- For reasons of saving energy, in particular, it is endeavored to use conventional semiconductor components to generate light since they are highly efficient. Semiconductor components of this type are also known as LEDs.
- It could therefore be helpful to provide a light-emitting surface element, and a method for producing the latter, which can be produced with high reliability in conjunction with low radiation losses.
- We provide a light-emitting surface element including a connection device, a light-generating element having at least two connections electrically conductively connected to assigned connection lines on the connection device, and at least one planar light-guiding element formed by injection-molding in a manner at least partly embedding an arrangement composed of connection device and light-generating element in the planar light-guiding element.
- We also provide a method for producing a light-emitting surface element including providing a connection device, arranging a light-generating element on the connection device, and producing a planar light-guiding element by injection-molding in such a way that the light-generating element and the connection device are at least partly embedded into the light-guiding element.

FIG. 6 shows a variant of the configuration illustrated inFIG. 1 . - As a result of the production of the planar light-guiding element by the injection-molding method, a light-generating element and a connection device are embedded into the light-guiding element, such that, first, the coupling of light into the light-guiding element is made possible with high efficiency as a result of the avoidance of interfaces abutting one another and, second, it is possible to form a stable connection between the planar light-guiding element and the arrangement composed of connection device and light-generating element.

- As a result of a conversion means being applied on the light-emitting diode mounted as “chip size package” on the connection device, the mounted arrangement is protected against impairments during injection molding. Furthermore, the coloration can thus be determined at a very late time in production.
- Our elements and methods are described below on the basis of examples with reference to the drawings. Identical reference symbols indicate identical elements in the individual figures, but the illustrations do not show relationships to scale.
-
FIG. 1 shows an example wherein aflexible strip material 7 is provided, which has through openings 9 spaced apart at a constant distance.Conductor tracks 6 composed of electrically conductive material are applied on thestrip material 7. This application process can be effected for example by printing technology or by lamination. In this case, theconductor track 6 can either firstly be applied over the whole area and then acquire the desired form by means of an etching method, for example, or be applied directly in the desired form. Printing technology, in particular, is recommended for the latter option. - Furthermore, provision is made of a light-generating element such as an
LED 3, for example, which is formed as a so-called “chip size package,” alternatively called CSP 1. In this case, CSP 1 consists of acarrier 2 on which theLED 3 is formed. The connection contact-making of theLED 3 is provided on thecarrier 2 in a manner not illustrated in detail. Thecarrier 2 in turn has connection contacts connected to theconductor tracks 6, for example, by means offlexible bumps 5. During operation, theLED 3 is then intended to emit visible electromagnetic radiation from the side remote from thecarrier 2. - As an option, provision is made for applying a conversion layer 4 on this surface which emits the light, the conversion layer altering the coloration of the light. This means that the wavelength of the emitted light is converted into a light having a different wavelength. In this way, by way of example, blue light emitted by an LED can be converted into white light with high efficiency.
- The arrangement described up to this point, composed of
CSP 1 andstrip material 7 provided withconductor track 6, is then surrounded by a planar light-guidingelement 8, such that the arrangement is embedded in the planar light-guidingelement 8. This embedding is preferably effected in the form such that the preassembled arrangement composed ofCSP 1 andstrip material 7 is introduced into an injection mold and the injection mold is then filled by a thermoplastic material. During injection molding, the thermoplastic material also penetrates through the through openings 9, thus resulting in an intimate and stable connection between the planar light-guidingelement 8 and thestrip material 7 after curing. -
FIG. 2 shows this arrangement again in a manner rotated by 90 degrees. It can be discerned here that the planar light-guidingelement 8 has approximately the thickness of theCSP 1. The extent to which the planar light-guidingelement 8 extends further on that side of thestrip material 7 which is remote from the CSP depends solely on mechanical preconditions. - Since the light is emitted from that side of the
LED 3 which is remote from the carrier, the light does not propagate and is not passed on below thestrip material 7. For reasons of stability or for reasons of shaping, however, it may be desired to provide the injection-molded material not only as far as penetration through the strip material, but also beyond that, as is indicated in the figures. - Two small elevations 10 are indicated at the surface of the light-guiding
planar element 8. The elevations are intended to indicate surface configurations by means of which the light is coupled out. Normally, the light emitted by the LED is guided in the planar light-guidingelement 8 and reflected inward again as soon as the light impinges on the outer edge. If the light passes to locations which are identified by the reference symbol 10 and modulate the surface, an altered angle of incidence is present for the light coming from inside at the surface such that the light is no longer reflected inward, but rather is emitted outward. In this way, the emission at the surface of the planar light-guiding element can be set by means of a corresponding configuration of the surface. -
FIG. 3 shows thestrip material 7 with the through openings 9 in plan view.Conductor tracks 6 are led in pairs at uniform distances, the conductor tracks being led more closely to one another at the location at which aCSP 1 is provided for mounting. Over and above their function described with reference toFIGS. 1 and 2 , the through openings 9 are also advantageous when thestrip material 7 is populated in a manner coming from a roll and is then intended to be rolled up again. The through openings 9 can then be used for exact transport and/or for exact positioning of thestrip 7. This also holds true, of course, when thestrip material 7 is introduced into the injection mold and positioned there. Thewindow openings 11 serve to ensure that, during the injection molding, the planar light-guiding element can extend around thestrip material 7 and in this case, as can be discerned inFIG. 2 , projects only insignificantly further beyond theCPS 1. - In
FIG. 5 , this more or less continuous arrangement fromFIG. 3 is illustrated in a more highly simplified manner in a view corresponding toFIG. 1 . The planar light-guiding element can be formed as it were correspondingly continuously like the strip and be divided at desired distances for the purpose of separation after curing. In accordance withFIG. 5 , a separating gap 10 is illustrated in each case centrally between twoCSPs 1, along which gap the individual light-emitting planar element is separated. This can be done by means of a suitable cutting method, for example. - However, it is also conceivable either for a respective injection mold to be used for an individual light-emitting surface element or for the injection mold to be configured in such a way that it has tapered portions or partitions, such that the individual light-emitting surface elements can correspondingly be separated by breaking-off, if appropriate, at the locations provided with the reference symbols 10 in
FIG. 5 . - However, it is also not absolutely necessary that only an individual light-generating
CSP 1 is provided for each light-emitting surface element. The number depends ultimately on the desired luminous intensity and the size of the surface to be formed and illuminated. In accordance withFIG. 4 , this is indicated in a form such that threeCSPs 1 are chosen in the case of the example illustrated inFIG. 4 . - Referring to
FIG. 1 , it is indicated that a conversion layer 4 is applied on theLED 3 to convert the natural light generated by the LED into a desired light. In a configuration such as is illustrated inFIG. 6 , the arrangement differs from the arrangement illustrated inFIG. 1 only insofar as initially the conversion layer 4 is absent. Instead of this, a conversion covering 4 a is applied in a manner enveloping theCSP 1. This can be applied, for example, as a drop or in an injection method. Which method is ultimately chosen depends solely on the technical possibilities and on the state in which theCSP 1 is intended to be tested beforehand prior to mounting on the strip material.
